HELENA, Mont. (AP) - Two adversaries who duked it out repeatedly over gun legislation during the session are now continuing their disagreement before the state Commissioner of Political Practices.

Helena Mayor Jim Smith, who is also a lobbyist for law enforcement groups, has filed a complaint alleging that Gary Marbut of the Montana Shooting Sports Association improperly failed to register as a lobbyist.

Under state rules, anyone who spends more than $2,400 trying to influence lawmakers must register as a lobbyist.

Marbut says he does not meet the state's definitions of a lobbyist, because he is not paid to crusade for gun freedoms.

Commissioner of Political Practices Dennis Unsworth says investigating the complaint will likely take six to eight months.
